“…if the attacks of the evil spirit are strong, if the persecution with our passions is unending, then we must all the more put on all the armor of God to resist the machinations of the evil one. Keeping the mind from vain thoughts, the heart from corrupt desires, the will from spiritually harmful undertakings and intentions, we must also do everything possible to keep ourselves from every situation that is dangerous for our internal and external purity.”
(Archbishop Evlampy (Pyatnitsky) on ‘External and Internal Fasting’)
